Magnetocentrifugal Origin for Protostellar Jets Validated through Detection of Radial Flow at the Jet Base

چکیده
Jets can facilitate the mass accretion onto protostars in star formation. They are believed to be launched from disks around by magneto-centrifugal force, as supported detections of rotation and magnetic field some them. Here we report a radial flow textbook-case protostellar jet HH 212 at base further support this jet-launching scenario. This validates central prediction theory formation collimation, namely, is densest part wide-angle wind that flows radially outward distances far (small, sub-au) launching region. Additional evidence for flowing component comes its ability reproduce structure kinematics shells detected jet. component, which transport material inner outer disk, could account chondrules Ca-Al-rich inclusions Solar System large distances.

The radial structure of protostellar accretion disks: influence of jets
Context. The radial structure of accretion disks is a fundamental issue regarding star and planet formation. Many theoretical studies, focussing on different aspects such as e.g. disk emissivity or ionization, have been conducted in the context of the Standard Accretion Disk (SAD) model, where no jet is present. Aims. We wish to calculate the structure of YSO accretion disks in an approach that...
متن کاملThe origin of the protostellar jet GGD 34 ?
GGD 34 is a protostellar jet with wiggles which are accompanied by “sine-like” variations in the radial velocity of the emitting material by as much as 60 km s−1. Thus GGD 34 is an interesting object to understand the physical mechanisms involved in the generation of wiggles in protostellar jets. In this work we present high resolution images obtained with the Canada-France-Hawaii Telescope (CF...
متن کاملThe resummation of inter-jet energy flow for gaps-between-jets processes at HERA
We calculate resummed perturbative predictions for gaps-between-jets processes and compare to HERA data. Our calculation of this non-global observable needs to include the effects of primary gluon emission (global logarithms) and secondary gluon emission (non-global logarithms) to be correct at the leading logarithm (LL) level. We include primary emission by calculating anomalous dimension matr...
متن کاملThe First Jet in the Universe: Protostellar Jets from the First Stars
The protostellar jets driven by the formation of the first stars are studied by using three-dimensional magnetohydrodynamical (MHD) nested grid simulations. Starting from a slowly rotating spherical cloud of 5.1× 10M⊙ permeated by a uniform magnetic field, we follow the evolution from the central number density nc = 10 3 cm (where the radius of the object r = 6.6 pc) to nc ≃ 10 23 cm ( r ≃ 1R⊙)...
